SHAVING BRUSH.

Application led January 22, 1920, Serial No. 353,132. Renewed .Tune 21,1922. Serial No. 569,880.

and State of Tennessee, has invented certain new and useful Improvementsin Shavlng Brushes, of which the following is a specification.

This invention relates to improvements in shaving brushes.

The prime object of the invention is to provide a brush with a reservoirfor receiving plastic soap, and means for ejecting same into thebristles, and so arranging the parts as to form a vacuum in the reservoir to withdraw surplus soap after use of the brush, to prevent waste.

A further object of the invention is to provide a brush mounting topermit of the convenient assemblage or separation of the parts tomaintain the brush in a sanitary condition. f

A still further object of the invention is to provide a brush structurehaving a plastic soap reservoir, and a powder container which 1sabsolutely water-proof.

Another object of the invention is the provision of duct or tubularmeans for expressing the soap to the bristles, and arranging the brushhead and associated parts to form a frictional grip between the handle,brush head and tubular means for convenience in holding the elementstogether.

The invention also comprehends improvements in the details ofconstruction and arrangement of parts which will be hereinafterdescribed and particularly pointed out in the claims.

In the accompanying drawing:

Fig. 1 is a sida elevation of my improved brush.

Fig. 2 is a vertical, central section of the same.

Fig. 3 is a detailed prospective View of the combined powder containerand soap plunger. j

Fig. 4 is a detailed View of the brush head.

The numeral 1 indicates a cylindrical reservoir which is internallykthreaded as at 3. Engaging the threads 3 at the lower end of thereservoir is an inverted bottom cup member 4, provided with a shoulder5, against which the lower edge of the cylindrical reservoir seats. Thecup member 4 is hollow on its under side, as shown at 6,

vtom edge of the cup member.

and is further provided with a central tube 7, which extends below thepiane of the bot- The top of the cup member is flat, and forms thebottom wall of the reservoir, and the opening through the tubecommunicates with the said reservoir to provide a passage for theplastic soap.

Fitting within the hollow portion 6 of thc cup member, is a brush head8, formed with a central opening 9, and hollow on its under side, asshown at 10'. Depending centrally in the hollow portion 10, is anoutwardly tapering projection 11, through which the opening 9 extends,and the inner side wall of the hollow portion of the head is corrugatedas at 12. The bristles forming the brush are forced into the hollowportion 10, and are confined between the tapered wall 11, and thecorrugated wall 12 which serves to maintain said bristles in the fixedposition in the head. By this construction a cavity 13, is formed in thecenter of the bristles to receive a rubber or other flexible tubularmember 14, frictionally supported on the tube 7. The opening 9, in thebrush head is of suiiicient diameter to permit the tubular rubber member14, topass therethrough when the parts are assembled, as clearly showniu Fig. 2.

The brush head frictionally engages the wall 6 of the bottom cup member,while the wall of the opening 9, frictionally'engages the rubber tubularmember 111. This frictional engagement between the head and the cupmember forms a means for holding the brush in fixed relation, and is onewhich permits ready and convenient assemblage or removal of the parts.Engaging the threads 3, of the cylindrical yreservoir 1, is a hollowplunger 16, formed at its lower end with a threaded portion 17, andprovided at its upper end with threads 18, below which is an annularfiange 19. Snugly fitting over the cylindrical reservoir 1 is a sleeve20, Vthe upper end of which engages with the flange 19, and in thesleeve, below the flange are vent openings 21, to permit the exit of airas the plunger is adjusted in or out in the reservoir, when using thebrush. This sleeve constitutes an enclosing or finishing member betweenthe cylindrical reservoir 1, and the hollow plunger, while the openings21 prevent the accumulation ot K interiorly screw-threaded, as at 23,and engaging the same is a cup shaped cover 24, provided with an opening25. Fitting over the cover, and engaging the threads 18, on the plungeris a cap 26.

Assuming the parts are in the position shown in Fig. 2 and plastic soapis in the reservoir between the bottom of the plunger 16, and the bottomcup member 4, and powder is in the hollow portion of the plunger 16,- byturning the cap 26, it engages the flange 19, and forces the sleeve downon the outer surface of the plunger and expels the air from between theparts through the openings 21, and also forces the plunger down on thesoap and expels the same through the tubes 7 and 14 and into the centerof the` bristles. Obviously, when the bristles are moistened, theplastic soap is converted into lather, the rubber tube readily yieldingwhen the brush is used.

After the brush has been used, the plunger is rotated slightlyvin theopposite direction, which creates a partial vacuum in the reservoir, theexcess plastic soap in the tubes being thereby withdrawn into thereservoir, so that when the bristles are subsequently washed, there isno chance-of the soap remaining in the bristles, thus avoiding thepossibility of an uns'anitary condition aris-` ing with the bristles.

The construction described has been designed to produce a` practical,convenient and sanitaryy shaving brush.y It folglgows' from theforegoing description that the expulsion of the plasticsoap into thebristles will be such that thel soap vwill be sustained within thebristles until worked up into lather, and that liability of the soap`being retained in the bristles after the plunger is withdrawn ispractically impossible. The hollow plunger contains' powder, and aftershaving the cap is removed from the handle and the brush is inverted andthe powder` is sifted through theopening 25. The arrangement of thecover 24, prevents undue waste of the powder, and when the cap isapplied it serves as a cover for the opening as well as a Iconvenientknot for rotating the plunger.

What I claim is:

1. A shaving brush comprising a handle, an inverted cup arranged in thelower end of the handle a-nd having a central tube projection openingAthru the cup, a flexible tube fitting over the tube projection andextending below the same, a brush head having a Wall fitted within theinverted cup and an annular projection within said wall adapted tooverlie the fieXible -tube to bind said flexible tube between said walland the wall projection of the cup, the space between the wall andannular projection of the brush head being formed to receive the brushbristles.

2. A shaving brush comprising a handle formed at its lower end with aninverted cup from which depends a tube, a rubber tube forced o-n thefirst mentioned tube, a hollow brush head having a central projectionformed with an opening, the rubber tube frictionally engaging the wallof the opening and the side of the brush head frictionally engaging thewall of the inverted cup on the handle to lock the head and handletogether, and a plunger in the handle to force soap through the tubes tothe bristles.

3. A shaving brush comprising a hollow internallythreadedy handle, aninverted cup having a reduced portion externally threaded and engagingthe internally threaded portion of the handle, the inverted cup having la central reduced tubular extension, a ilexible tube frictionall'y heldon the tubularextension and depending below the latter, a brush headhaving a central projection, the brush head frictionally engaging thewalls of the inverted cup and the central projection frictionallyengaging the flexible tube and binding the same on the .tubularextension of thecup, whereby to hold the brush head on .the handle, andaplunger for forcing soap thru the tube to the bristles of the brush.

In testimony whereof I aflix my si ature.
